Yeah, I go the minimalist route. I have a non mapping gps (garmin gecko 301 and garmin foretrex 101). With either, set to UTM for waypoints, it will give me my coordinates in UTM (universal transverse mercator, metric) and I transfer them to my UTM gridded map to find out where I am or mark places. By not leaving the gps on for tracks or routes, I save batteries.
